Description

Technical Field

[0001] This utility model relates to an air fryer. Background Technology

[0002] Air fryers, as a new type of kitchen appliance, are favored by consumers for their ability to quickly cook healthy food without using large amounts of oil. Heating efficiency and user experience are two important considerations in the design of air fryers. To enhance the user experience, many air fryers are equipped with a transparent window, allowing users to easily observe the cooking process of the food inside. However, to achieve this function, please refer to... Figures 1-2 In existing technologies, a stainless steel heating element 100 and a halogen lamp assembly typically work together. The stainless steel heating element 100 heats the food, while the halogen lamp assembly provides illumination, allowing the user to clearly see the cooking process inside the fryer. However, this design faces several problems in practical applications. First, the addition of the halogen lamp assembly restricts the internal space layout of the air fryer, particularly in the design of the air duct structure, necessitating the inclusion of a clearance groove 200 to accommodate the lamp assembly. This clearance design results in an irregular air duct shape and scattered hot air distribution, thus affecting the overall heating effect. Furthermore, the increased complexity of the air duct increases the difficulty of production and assembly, reducing manufacturing efficiency and increasing costs. Second, in the assembly process of existing air fryers, the installation of the heating element often requires overcoming structural layout and space constraints. Traditionally, the stainless steel heating element 100 is usually fixed inside the fryer with screws or clips. However, this installation method is not only time-consuming and labor-intensive but also prone to interference within the limited internal space, leading to low assembly efficiency. (See also...) Figure 1 The arrow points to a schematic diagram of the air ducts. Multiple air ducts are arranged at uneven intervals, with irregular shapes and scattered distribution. Utility Model Content
